When a task is running on a device, a window or image may appear on the screen, providing information about the task’s progress, such as the elapsed or remaining time. This fleeting window serves two main purposes: informing the user about the ongoing activity and keeping them engaged until it finishes. In some cases, when an application takes a while to load, this window can be used to display information about features, special offers, or other complementary services. On the internet, these fleeting windows are often used as homepages, aiming to keep users engaged while the site loads. They can also be used to filter visitors based on criteria such as country of origin, preferred language, age (particularly for sites related to alcohol, online gaming, or pornography), or connection quality. In French, the term “splash screen,” borrowed from English, is commonly used in professional settings to refer to this type of window.
